The TPM1 gene is associated with autosomal dominant hypertrophic cardiomyopathy (HCM) (MedGen UID: 183649), dilated cardiomyopathy (DCM) (MedGen UID: 2880), and left ventricular noncompaction cardiomyopathy (LVNC) (MedGen UID: 349005).

Invitae tests that include this gene:
Pathogenic TPM1 variants are associated with 1%-2% of clinical cases of DCM and 1% of HCM cases. The percentage of LVNC cases associated with pathogenic variants in the gene is unknown.
The TPM1 gene encodes the protein tropomyosin alpha-1 chain. Tropomyosin is a part of the sarcomere complex, which is present in both cardiac and skeletal muscle cells. The primary role of the sarcomere complex is muscle contraction. Pathogenic variants in genes that encode sarcomere proteins are a common cause of inherited cardiomyopathies.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
